my boyfriend.

I can't really explain how he makes me feel because the feelings vary.Sometimes I love the death out of him and then other times I just think "why did I ever get into this relationship.I'm not quite sure what I'm going to do yet.I don't know if he is the right guy for me and that worries me because I really care about him but he just makes it so difficult to love him sometimes.He is the most selfish guy I have ever met.I'm so confused.
